After reading the programming manual I am quite confident that I will be able to program my original sequence using 3 level sensors as the water change and ato function allows for 1 sensor to perform 2 functions depending on which mode it is in. I believe that programmable logic should allow me to customise these functions.

As i seem to be having no luck on this forum in the a way of a confirmation from a moderator or anyone else I guess I am now just going to purchase the system and go for it!

I guess the only way of proving anything in life is by actually doing it! If anyone is actually interested and it doesn't seem anyone is (I may as well be talking to myself right now haha) I will post back here in any case and hopefully with the succesfull programming instructions for people should they ever want to automate large water changes in their systems.

I will also do a youtube video as well which if this works, would help to promote the profilux 3 system.

Bye for now
